BUTTON-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 7 ,93 dated- F a y1903- Applioation filed November 7, 1901. Serial No. 81,446. (No model.)

1'0 all w/tom it may concern.-

Be it known that we, GEORGE W. GWINN, and HENRY C. SMITH, citizens ofthe United States, residing at Baltimore, in the State of Maryland, haveinvented certain new and useful Improvements in Button-Setting Machines,of which the following is a specification.

This invention relates to an improved machine for attaching buttons togarments by means of a staple or other similar fastener; and theinvention consists of a machine having substantiallythe parts andcombination of parts hereinafter more particularly shown, described, andclaimed.

Referring to the drawings, Figure 1 is a side elevation of our machine,partly in section and showing the parts in their normal position. Fig. 2is a detailed plan view, partly in section, of the magazine. Fig. 3 is arear elevation of the magazine, partly in section. Fig. 4 is a detailedview of the magazine, partly broken away, showing the pawls lifted fromthe slots ready to transfer to the next slot. Fig. 5 is asimilar viewshowing the position of the pawls after advancing one slot.'

Fig. 6 is a detailed View, on an enlarged scale, of the upper portion ofthe'machine, partly in section and showing the plunger and the 0perativeparts of the chuck. Fig. 7 is a detailed longitudinal section of thechuck, showing a staple in position to be driven. Fig. 8 is a detailedView of one of the jaws of the chuck.

Similar numerals designate throughout the several views.

Referring to the accompanying drawings, forming part of thisspecification, 1 designates a stand or table to which is secured abase-plate 2, in which the plunger 3 reciprocates. The plate 2 issecured to the stand 1 by means of bolts or other suitable means and hasa laterally-projecting arm 5, which latter is providedwith a magnetizedcollar 6 to hold a metal button thereto,and a clencher 7, across whichthe bar of the button projects. The said clencher 7 is in line with thetravel of the plunger 3 and serves to clench or curl the legs of thestaple around the bar of the button.

like parts The plunger 3 carries on its front end a chuck 8, whichlatter has its lower surface resting upon the stand or table 1 and isformed with a shoulder 21 on itsupper surface at the rear thereof. Thesaid chuck 8 is provided with two jaws 9, pivoted thereto at 10 and areheld normally closed by means of the springs 11. Thejaws 9 are providedwith a concavity 12 for the reception of the staples as they fall fromthe raceway 28 one at a time. The rear ends of the said jaws 9 are cuton an incline to permit the front ends thereof to be forced apart. Thefront ends of the said jaws 9 are concaved at 12 and taper toward thefront to an opening 13, through which the legs of a staple project.Secured within the jaws 9 are auxiliary jaws l4, pivoted at 15, whichare held in their normal position by the springs 16. These jaws 14; fiton each side of the legs of the staple and serve to hold the said staplein its proper position ready to be forced through the opening 13 in thefront of the jaws and clenched around the bar of the button by theplunger3.

The plunger 3 is reciprocated through the medium of the treadle 17,lever 18, toggle-levers 19, and the rock-arm 20. As the plunger movesforward it carries the chuck 8 forward until the shoulder 21 on thechuck comes in contact with the pin 22, when the said chuck will be heldwhile the plunger 3 continues to move forward. As the plunger 3continues to move forward it carries in front of it a staple which haspreviously been deposited in the cavity 12 with the head thereof back ofthe jaws 14.- and the legs being held in line with the opening 13 by thesaid jaws 14; and forces the auxiliary jaws 14E apart against thetension of the springs l6and also forces the jaws 9 apart against thetension of the springs 11. The legs of the staple straddle the bar of abutton held to the collar 6 and I are forced against the clencher 7 andare curled around and secured to the button.

When the plunger returns, the jaws 9 will 5 hold fast to the end of thesaid plunger and be carried back with it until the rear end of the chuckcomes into contact with the plate 23,

against which the said chuck will be held while the plunger continuesback until the I06 rested. The plunger 3 is provided with setscrews tolimit its forward movement.

The machine is provided with a magazine to hold the staples and to feedthe latter to the chuck one at a time. The magazine is supported by abracket 26, secured to the plate 2 by a bolt 27 and has a raceway 28,leading from the magazine to the chuck, through which the staples arefed. The bottom 29 of the magazine is stationary and is held to thebracket 26 by means of the bolt 30. Extending through the bottom of themagazine is a shaft 31, on which is secured a pinion 32. A rack 33 gearswith the pinion 32. The rack 33 is connected at its outer end to a rockarm 34, which latter is con nected to the rock-arm 20 by a link 35 andis operated by the mechanism which operates the plunger. The magazine isprovided with an annular inner wall or ring 36, which is provided withan annular flange 37 at its upper end and a projection 38. Thisprojection 38 is provided with a downwardly-projecting perforated boss39, which fits over and is secured to the upper end of the shaft 31,which causes the said ring 36 to revolve with the shaft 31. The ring 36isprovided at its lower edge with a number of slots 40, (in the presentinstance siX,) through which the staples fall to the outer ring. At therear of the ring 36 is'an upwardly-projectinglug 41 to which is pivotedthe pawls 42 and 43, the latter having a laterally-projecting pin 44.These pawls 42 and 43 are held to their normal position by the springs45. Secured to the bottom 29 and projecting upwardly in line with thetravel of the pin 44isa cam 46. The inner ring 36 is provided with arecess 47 at its lower edge. The outer ring 48 fits around the innerring 36, rests upon the bottom-29, and is flush with the flange 37 andthe bottom 29. The upper end of the ring 48 is provided with a number ofapproximately V- shaped slots 49, arranged at equidistant intervals, inwhich the pawls 42 and 43 rest. The lower edge of the ring 48 is alsoprovided with slots 50, corresponding in shape to the slots in the innerring, through which the staples fall to the raceway. These slots arearranged to register with the slots in the inner ring 36. Secured to theflange 37 of the inner ring 36 is a metal plate 51, extending downwardlyand covering a number of the slots in the outer ring. The bottom 29 isprovided with an opening 52, into which is fitted a stop 53. This stopis pressed upward against the inner ring 36 by the spring 54.

The operation of the machine is as follows: After the staples have beenplaced in the magazine and one has been fed to the chuck through theraceway 28 the machine is then ready for operation. The treadle 17 ispressed down, which imparts motion, through the rod 18, toggles 19, androck-arm 20, to the plunger 3, causing the latter to move forward. As

the plunger 3 moves forward it carries the chuck 8 with it until theshoulder 21 comes in contact with the pin 22, when the chuck will beheld while the plunger 3 continues to move forward. As the plungercontinues to move forward it carries in front of it a staple and forcesthe auxiliary jaws 14 apart against the tension of the springs 11. Asthe staple is pushed out its legs will straddle the bar of the button,held against the collar 6, and be forced against the clencher 7 by theplunger and caused to curl around the bar of ,the button and secure thelatter to the garment. When the plunger returns, the jaws 9 will clampthe end of the plunger and remain open until the chuck 8 comes intocontact with the plate 23, when the said chuck will be held, while theplunger 3 continues back, until the lug 24 comes into contact with theplate 23 and the rearward movement of the plunger arrested. When thetreadle 17 is pressed downward to operate the plunger, motion will betransmitted through the rod 18, toggle-levers 19, rock-arm 20, rod 35,and rock-arm 34 to the rack 33. As the rack 33 reciprocates it revolvesthe pinion 32 and shaft 31,which latter rotates the inner ring 36. Theslots 40 of the inner ring 36 register with a corresponding number ofslots 49 in the outer ring 48, and as the outer ring is reciprocated thestaples fall through the slots of the inner and outer rings and restagainst the plate 51. The inner and outer rings are held together by thepawls 42 and 43, as shown in Figs. 1 and 3. As the inner ring 36 turnsit carries the outer ring with it until the pin 44 comes into contactwith the cam 46, when the pawl 43 will be lifted out of the slot and atthe same time the stop 53 will be forced up into the recess 47 of theinner ring 36 by the spring 54 and also into one of the slots of theouter ring and will assume the position shown in Fig. 4. The outer ringwill be held by the stop 53, as seen in Fig. 4, until the inner ring hastraveled the distance sufficient to permit the pawls 42 and 43 toadvance one slot, as seen in Fig. 5. When the pawl 43 is lifted out ofthe slot and is being advanced to another slot, the pawl 42 will rideout of its slot, owing to the inclination of the pawl and slot, andadvance with the ring 36 to the next slot. When the inner ring isreturned, it carries the outer ring back, which latter rides over theinclined surface of the stop 53, pressing it down, in which position itis held by the inner ring 36. It will be seen that while the inner ringreciprocates back and forth the outer ring advances a distance equal tothe distance between the V-shaped slots 49. The pawl 43 carries theouter ring in one direction and the pawl 42 in opposite direction. Whenthe outer ring 48 is held by the stop 53 and the inner ring moves thedistance from one V-slot 49 to another, the metal plate 51, secured tothe outer ring, will uncover one of the slots 49 and allow one staple tofall into the raceway and be conveyed to the chuck. It will be seen thateach time the inner ring is reciprocated the outer ring 48 will advanceone slot and one slot in front of the raceway will be uncovered andallow one staple to pass into the raceway.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent of the United States, is

1. The combination with a button-setting machine, of a magazine forholding staples, comprising a stationary bottom; an inner ring revolublysecured to said bottom and having a plurality of slots in its loweredge; an outer ring having a plurality of slots in its lower edgearranged equidistant around the entire edge; means to hold the saidinner and outer rings together; and means to reciprocate the said innerring, as and for the purpose described.
